Good news Rhapsody fans; an app has finally been submitted to Apple. If approved, it will give iPhone/iPod Touch owners with a $15-a-month Rhapsody To Go account unlimited-streaming over Wi-Fi, 3G and Edge. Here's what it looks like in action:

The screenshot is courtesy of a Gdgt hands-on, which explains that "unlike Spotify's yet-to-be-released iPhone app, Rhapsody's app lacks offline capability." No local storage until version 2.0, apparently. Bummer.

Even if the app is approved (that is, Apple doesn't balk at competition to iTunes on its own device), you kinda get the feeling it'll be a tough sell beyond existing subscribers until they get the local storage sorted. In the meantime, the company plans a limited time free-trial, and an Android version. From its blog:

"We are working diligently on an Android app and once we're done there, we plan to turn our sights on more mobile platform and carrier app stores"
